Definitions

  • US 6634596 B2 describes an integrated aircraft system.
  • FR 2944259 A1 describes an electric power generating device for aircraft.
  • US 2006/010875 A1 describes a gas turbine engine bleed power assist system and method.
  • a crossover conduit 310 with a crossover valve 312 fluidly connects first bleed air conduit 108A with second bleed air conduit 108B.
  • Crossover valve 312 is configured and adapted to place both of first generator arrangement 302 and second generator arrangement 304 in fluid communication with a common compressor section.
  • both first generator arrangement 302 and second generator arrangement 304 receive motive flows of high pressure bleed air from APU 12C. This allows for supplemental electrical load 26 (shown in Fig. 1 ) to be powered by APU 12C, which can in turn be started and stopped as necessary during flight for purposes of powering supplemental electrical load 26.
